13-16) High Frequency OCC BW
Measure OCC BW dB Down – Control Byte #97 (61h)
Description: Measure OCC BW with dB down method.
If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale factor of
the module. If the module is not attached, frequencies are sent in Hz. Use Control Word A203 to determine whether a module
is attached and the appropriate scale factor.
